Systems and methods for locking queued distributed network tokens

ABSTRACT

The disclosed systems and methods provide non-native functionality to a distributed network for events management on a blockchain via locking queued distributed network tokens. The disclosed technology receives a transfer event request from a first node associated with a first token storage, where the transfer event request corresponds to movement of a requested token amount that is associated with at least one token. A pending transfer event log that queues pending transfer event requests is accessed and modified by adding the transfer event request to the queue of pending transfer event requests. This causes the at least one token associated with the transfer event request to be locked, thereby preventing its association with other transfer events. The transfer event request is then transmitted to the distributed network, whereby the distributed network executes the movement of the at least one token.

FIELD OF TECHNOLOGY

The present disclosure generally relates to computer-based systems configured for permission events management on a blockchain and methods of use thereof.

BACKGROUND OF TECHNOLOGY

Typically, in a blockchain transaction environment “permissions” are commonly handled through N-of-M multi-signature (“multisig”) format. For example, sending from a “2 of 3” multi sig wallet would require that two of three parties consent to submit a transaction. In a blockchain sense, a transaction is not real until sent out and confirmed on the blockchain.

DETAILED DESCRIPTION

Various detailed embodiments of the present disclosure, taken in conjunction with the accompanying figures, are disclosed herein; however, it is to be understood that the disclosed embodiments are merely illustrative. In addition, each of the examples given in connection with the various embodiments of the present disclosure is intended to be illustrative, and not restrictive.

Throughout the specification, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrases “in one embodiment” and “in some embodiments” as used herein do not necessarily refer to the same embodiment(s), though it may. Furthermore, the phrases “in another embodiment” and “in some other embodiments” as used herein do not necessarily refer to a different embodiment, although it may. Thus, as described below, various embodiments may be readily combined, without departing from the scope or spirit of the present disclosure.

In addition, the term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”

As used herein, the terms “and” and “or” may be used interchangeably to refer to a set of items in both the conjunctive and disjunctive in order to encompass the full description of combinations and alternatives of the items. By way of example, a set of items may be listed with the disjunctive “or”, or with the conjunction “and.” In either case, the set is to be interpreted as meaning each of the items singularly as alternatives, as well as any combination of the listed items.

FIGS. 1 through 9 illustrate systems and methods of pre-validating event requests before multisig permission on a blockchain. The following embodiments provide technical solutions and technical improvements that overcome technical problems, drawbacks and/or deficiencies in the technical fields involving blockchain event permissions that utilize a multi sig permission process for each event on the blockchain, even where events are duplicates or with respect to the same tokens. As explained in more detail, below, technical solutions and technical improvements herein include aspects of improved event validation efficiency to decrease blockchain resource demands by establishing pre-permission to prevent multiple use of individual tokens without requiring multisig permission.

In a pure blockchain transaction environment “permissions” are commonly handled through N-of-M multisignature (“multisig”). For example, sending from a “2 of 3” multisig wallet would require that two of three parties consent to submit an event. In a blockchain sense, a transaction is not real until sent out and confirmed on chain.

In some embodiments, rather than allow event requests (e.g., blockchain transactions) for more tokens than exist to be in be in the permission queue, tokens may be locked while in proposed (unapproved) event request. By using the permission queue to lock tokens while in a proposed state, subsequent event requests for the same tokens or for more tokens than exist in the user's wallet may be rejected before the locked event request or subsequent event request(s) are submitted to the blockchain. In some embodiments, without locking tokens in the permission queue, the tokens could be in the queue multiple times. For example, for a wallet with 1,000 tokens where user A is a maker and user B is an approver, user A may submit a send for 700 tokens and another for 1,000 tokens, and another for 800 tokens . . . and so on. As long as the tokens in the permission queue are not locked and remain available, user A can keep creating new (pending) sends which would require a large number of resources in a distributed network of the blockchain environment to process each request, including multisig permissions and denials. However, in using the permission queue to lock the tokens of the first send request, any subsequent requests can be approved or denied based on the tokens of the first send request being locked and removed from the wallet of user A. If the first send request is approved, the locked tokens are included in a transaction on the blockchain. If a transaction is rejected, the tokens are unlocked and returned to available in the wallet.

Based on such technical features, further technical benefits become available to users and operators of these systems and methods. Moreover, various practical applications of the disclosed technology are also described, which provide further practical benefits to users and operators that are also new and useful improvements in the art.

FIG. 1A depicts a block diagram of a distributed network architecture for event permission in a permission queue for submission to a blockchain in accordance with one or more embodiments of the present disclosure. FIG. 1B depicts a block diagram of a smart contract 151 including a mapping of user wallets on the blockchain 150 to user accounts in the asset database 140 in accordance with one or more embodiments of the present disclosure.

In some embodiments, a hybrid blockchain environment 100 may include nodes including user device 101 that interface with a blockchain 150 via one or more service layers. In some embodiments, the service layers may include, e.g., a front-end service 110, a workflow service 120 and a back-end service 130. Each user device 101 may submit event requests 102 that employ tokens on the blockchain by submitting the event request 102 via the front-end service 110. The front-end service 110 may engage the workflow service 120 to initiate a workflow based on the event request 102, which may employ the back-end service 130 to instruct the blockchain 150 as well as an asset database 140 to store, transfer, record or otherwise operate on asset records associated with the token(s) of the event request 102.

In some embodiments, the asset database 140 may track one or more state(s) of one or more asset(s) and/or operation(s) on asset(s) represented by token(s) of the blockchain 150. In some embodiments, the asset database 140 may be the source of truth for in-progress workflows with regards to event requests 102. Thus, states of the workflow may depend on entries in the asset database 140.

Using the asset database 140 as a source of truth provides resilient records in the case of a system outage. However, asset and operation states in the asset database 150 may become out of sync with tasks in the workflow due to, e.g., lag in acknowledgement of tasks and/or states. Accordingly, in some embodiments, the workflow service 120 may track the state of each event request 102 in order to maintain a synchronized source of truth. In so doing, the workflow service 120 may track states of each token in each event request 102 and lock each token and/or token quantity while in an in-progress workflow.

In some embodiments, the hybrid blockchain environment 100 may receive event requests 102 from one or more user devices 101 that interface with the front-end service 110. In some embodiments, the hybrid blockchain environment 100 may be a part of the user computing device 101. Thus, the hybrid blockchain environment 100 may include hardware and software components including, e.g., user computing device 101 hardware and software, cloud or server hardware and software, or a combination thereof.

In some embodiments, the hybrid blockchain environment 100 may include hardware components such as one or more processors, which may include local or remote processing components. In some embodiments, the processor(s) may include any type of data processing capacity, such as a hardware logic circuit, for example an application specific integrated circuit (ASIC) and a programmable logic, or such as a computing device, for example, a microcomputer or microcontroller that include a programmable microprocessor. In some embodiments, the processor(s) may include data-processing capacity provided by the microprocessor. In some embodiments, the microprocessor may include memory, processing, interface resources, controllers, and counters. In some embodiments, the microprocessor may also include one or more programs stored in memory.

Similarly, the hybrid blockchain environment 100 may include storage, such as one or more local and/or remote data storage solutions such as, e.g., local hard-drive, solid-state drive, flash drive, database or other local data storage solutions or any combination thereof, and/or remote data storage solutions such as a server, mainframe, database or cloud services, distributed database or other suitable data storage solutions or any combination thereof. In some embodiments, the storage may include, e.g., a suitable non-transient computer readable medium such as, e.g., random access memory (RAM), read only memory (ROM), one or more buffers and/or caches, among other memory devices or any combination thereof.

As used herein, term “server” should be understood to refer to a service point which provides processing, database, and communication facilities. By way of example, and not limitation, the term “server” can refer to a single, physical processor with associated communications and data storage and database facilities, or it can refer to a networked or clustered complex of processors and associated network and storage devices, as well as operating software and one or more database systems and application software that support the services provided by the server. Cloud servers are examples.

As used herein, terms “cloud,” “Internet cloud,” “cloud computing,” “cloud architecture,” and similar terms correspond to at least one of the following: (1) a large number of computers connected through a real-time communication network (e.g., Internet); (2) providing the ability to run a program or application on many connected computers (e.g., physical machines, virtual machines (VMs)) at the same time; (3) network-based services, which appear to be provided by real server hardware, and are in fact served up by virtual hardware (e.g., virtual servers), simulated by software running on one or more real machines (e.g., allowing to be transferred around and scaled up (or down) on the fly without affecting the end user). The aforementioned examples are, of course, illustrative, and not restrictive.

In some embodiments, the asset database 140 may be a database in the hybrid blockchain environment 100, or may be a database in communication with the hybrid blockchain environment 100. Accordingly, in some embodiments, the asset database 140 may be implemented either in direct communication with cloud server(s) to provide software services, e.g., controlled by the back-end service 130, or may be remote from the cloud server(s), e.g., via messaging across a network between the back-end service 130 and the asset database 140. In some embodiments, the asset database 140 may accessed directly via suitable database queries, or indirectly via suitable application programming interface (API) calls, or other suitable messaging data querying technologies or any combination thereof.

In some embodiments, the hybrid blockchain environment 100 may implement computer engines for the front-end service 110, workflow service 120, back-end service, asset database 140 and blockchain 150. In some embodiments, the terms “computer engine” and “engine” identify at least one software component and/or a combination of at least one software component and at least one hardware component which are designed/programmed/configured to manage/control other software and/or hardware components (such as the libraries, software development kits (SDKs), objects, etc.).

In some embodiments, the front-end service 110, workflow service 120, back-end service, and asset database 140 may be associated with and/or manage by the same administrator (e.g., enterprise). In some embodiments, the front-end service 110, workflow service 120, and back-end service may be associated with and/or manage by one entity/administrator (e.g., a first enterprise); and the asset database 140 may be associated with and/or manage by another entity/administrator (e.g., a second enterprise).

Examples of hardware elements may include processors, microprocessors, circuits, circuit elements (e.g., transistors, resistors, capacitors, inductors, and so forth), integrated circuits, application specific integrated circuits (ASIC), programmable logic devices (PLD), digital signal processors (DSP), field programmable gate array (FPGA), logic gates, registers, semiconductor device, chips, microchips, chip sets, and so forth. In some embodiments, the one or more processors may be implemented as a Complex Instruction Set Computer (CISC) or Reduced Instruction Set Computer (RISC) processors; x86 instruction set compatible processors, multi-core, or any other microprocessor or central processing unit (CPU). In various implementations, the one or more processors may be dual-core processor(s), dual-core mobile processor(s), and so forth.

Examples of software may include software components, programs, applications, computer programs, application programs, system programs, machine programs, operating system software, middleware, firmware, software modules, routines, subroutines, functions, methods, procedures, software interfaces, application program interfaces (API), instruction sets, computing code, computer code, code segments, computer code segments, words, values, symbols, or any combination thereof. Determining whether an embodiment is implemented using hardware elements and/or software elements may vary in accordance with any number of factors, such as desired computational rate, power levels, heat tolerances, processing cycle budget, input data rates, output data rates, memory resources, data bus speeds and other design or performance constraints.

In some embodiments, each of the front-end service 110, workflow service 120, back-end service, asset database 140 and blockchain 150 may include separate hardware and/or software components. Accordingly, in some embodiments, each of the front-end service 110, workflow service 120, back-end service, asset database 140 and blockchain 150 may include at least one processor(s) and at least one memory and/or storage solution, among other hardware and/or software components.

In some embodiments, the front-end service 110, workflow service 120, back-end service, asset database 140 and blockchain 150 may share one or more hardware and/or software components, such as, e.g., in a cloud environment and/or distributed network. Accordingly, in some embodiments, one or more of the front-end service 110, workflow service 120, back-end service, asset database 140 and/or blockchain 150 may share one or more processor(s) and/or one or more storage/memory solutions. Hardware components and software components of the blockchain environment 100 may be employed in any suitable combination of shared and/or dedicated forms to provide the front-end service 110, workflow service 120, back-end service, asset database 140 and blockchain 150.

In some embodiments, the user devices 101 may include or be incorporated, partially or entirely into at least one personal computer (PC), laptop computer, ultra-laptop computer, tablet, touch pad, portable computer, handheld computer, palmtop computer, personal digital assistant (PDA), cellular telephone, combination cellular telephone/PDA, television, smart device (e.g., smart phone, smart tablet or smart television), mobile internet device (MID), messaging device, data communication device, and so forth.

In some embodiments, the user devices 101 may include any computing device from electronic activities are performed or executed, such as, e.g., a terminal, personal computer, or mobile computing device for performing Internet-based and application-based activities (e.g., account logins, account information changes, online purchases, instant message communications, social media posts, among others and combinations thereof).

In some embodiments, the user devices 101 may include a physical terminal for performing electronic transactions, such as, e.g., a point-of-sale device, automated teller machine (ATM) or other device. As a result of a user executing electronic activities via the electronic activity execution device, data entries may be produced for entry into the user's account. For example, the electronic activity execution device may produce an electronic activity data entry.

In some embodiments, the front-end service 110 may provide an interface between the user devices 101 and the back-end service 130. In some embodiments, the front-end service 110 may include any user-facing part of the platform architecture, such as, e.g., subcomponents that make up the user experience. In some embodiments, the front-end service 110 may include a user interface and/or any software that allows platform software to be provided to the user devices 101, such as, e.g., a web browser, a client-side application, or other software enabling the user to interact with the hybrid blockchain platform 100 from a user device 101.

In some embodiments, the front-end service 110 may interact with the workflow service 120 and/or the back-end service 130. In some embodiments, the front-end service 110 may receive user inputs and user selections from the user devices 101 and convey data representing the user input and/or user selections to the workflow service 120 and/or the back-end service 130 via a suitable messaging and/or interface technology, such as, e.g., one or more application programming interfaces (API). In some embodiments, the term “application programming interface” or “API” may include a computing interface that defines interactions between multiple software intermediaries. An “application programming interface” or “API” defines the kinds of calls or requests that can be made, how to make the calls, the data formats that should be used, the conventions to follow, among other requirements and constraints. An “application programming interface” or “API” can be entirely custom, specific to a component, or designed based on an industry-standard to ensure interoperability to enable modular programming through information hiding, allowing users to use the interface independently of the implementation.

In some embodiments, the workflow service 120 may one or more applications, software, services, microservices and/or functions provided by the back-end service 130, such as, e.g., a cloud service or microservice. In some embodiments, the workflow service 120 may include one or more applications, services and/or functions for managing operations and components of the back-end service 130. Management software is in charge of allocating specific resources for certain tasks. Accordingly, in some embodiments, the workflow service 120 may include, e.g., middleware that interfaces between the back-end service 130 and the front-end service 110, an orchestrator and/or scheduler for the back-end service 130, or other software for coordinating and orchestrating resources of the back-end service 130 in a dynamic and real-time manner.

In some embodiments, the back-end service 130 may include one or more components of the hybrid blockchain platform 100 such as hardware and storage for providing one or more applications, servicers and/or functions to the user devices 101 via the front-end service 110 responsive to the user input and/or user selection. In some embodiments, the back-end service 130 may provide software functionality to the front-end service 110 via, e.g., one or more networks.

In some embodiments, the network may include any suitable computer network, including, two or more computers that are connected with one another for the purpose of communicating data electronically. In some embodiments, the network may include a suitable network type, such as, e.g., a local-area network (LAN), a wide-area network (WAN) or other suitable type. In some embodiments, a LAN may connect computers and peripheral devices in a physical area, such as a business office, laboratory, or college campus, by means of links (wires, Ethernet cables, fiber optics, wireless such as Wi-Fi, etc.) that transmit data. In some embodiments, a LAN may include two or more user devices 101 including, e.g., personal computers, printers, and high-capacity disk-storage devices called file servers, which enable each computer on the network to access a common set of files. LAN operating system software, which interprets input and instructs networked devices, may enable communication between devices to share the printers and storage equipment, simultaneously access centrally located processors, data, or programs (instruction sets), and other functionalities. Devices on a LAN may also access other LANs or connect to one or more WANs. In some embodiments, a WAN may connect computers and smaller networks to larger networks over greater geographic areas. A WAN may link the computers by means of cables, optical fibers, or satellites, or other wide-area connection means. In some embodiments, an example of a WAN may include the Internet and/or a blockchain network (e.g., the blockchain 150).

In some embodiments, to initiate a workflow, a user device 101 may instruct the front-end service 110 to issue an event request 102 with respect to a token storage, such as a cryptocurrency wallet or other wallet, of a node on the blockchain 150. In some embodiments, the user device 101 may be the node and/or may be associated with the node. In some embodiments, the event request 102 may include a request to perform a movement of tokens from the token storage to another token storage of another node on the blockchain 150, such as, e.g., another user device 101 and/or a token storage associated with the hybrid blockchain platform 100, e.g., associated with the asset database 140.

In some embodiments, the user device 101 may present an event control graphical user interface (GUI) for producing event requests 102, notifying the user of approved and/or rejected event requests 102, as well as other information such as user account information (e.g., for a user account in the asset database 140), user wallet information (e.g., associated with a blockchain wallet on the blockchain 150), etc. In some embodiments, the front-end service 110 may provide the event control GUI to a user device 101 to enable the user to select a particular event request related to an account operation and/or wallet operation.

In some embodiments, in response to the user selection of the particular event request 102, the front-end service 110 may issue the event request 102 to the workflow service 120 and/or the back-end service 130, e.g., via an API or other suitable interface and/or messaging technology. As described above, in some embodiments, the workflow service 120 may be an application, service or other software function implemented by the back-end service 130 for controlling a workflow associated with an event request 102, and/or the workflow service 120 may manage the back-end service 140 to implement the workflow associated with the event request 102.

Accordingly, in some embodiments, the event request 102 may be associated with a particular workflow for effectuating events on the blockchain 150 and/or in the asset database 140 to perform account-related operations. For example, in some embodiments, the event request 102 may include a request for a movement of assets and/or tokens with respect to another user. The movement may be subdivided into a workflow of tasks. For example, sending assets and/or tokens to a destination, such as to another user and/or to an omnibus account for conversion to an asset, may include the tasks of depositing assets to mint tokens for the first user, sending the tokens to the destination, and the redeeming the tokens in exchange for the assets at the destination. Thus, the sequence of tasks can be used to perform operations such a transfer of assets, a withdrawal of assets, a deposit of assets, among other operations using the blockchain 150 to provide a verifiable and immutable record for more efficient and secure operations. Other operations and workflows may implement.

Thus, in some embodiments, the workflow service 120 may identify a workflow associated with the event request 102 and exchange one or more task-related messages 104 with the back-end service 140 to implement the workflow. Because the workflow affects the movement of assets in a user account via the movement of tokens on the blockchain 150, the movement of assets is controlled by authentication by the blockchain 150. Indeed, the movement associated with each event request 102 is authenticated on the blockchain 150 before allowing assets to leave and/or enter a user account in the asset database 140. As a result, the movements in the asset database 140 between accounts, the movements of tokens on the blockchain 150, the issuance of event requests 102 may become out of synchronization upon multiple event requests 102 while the authentication of each movement is performed. As a result, events requested by event requests 102 may be rejected by the blockchain 150 in an unpredictable manner as some events achieve authentication faster before others in an asynchronous manner.

In some embodiments, to enforce synchronous events related to each user account and each associated token storage, the workflow service 130 may provide a source of truth for tracking in progress events in a sequential queue based on first-in-first-out ordering. Therefore, any particular event request 102 may be processed in the order that is submitted, thus preventing unpredictable and improper authentications, such as, e.g., double spend transactions, quantities of movement in excess of an account and/or token storage balance, among other improper authentications before requiring blockchain 150 resources. Table 1 below shows an example of an account record of the asset database 140 as a source of truth for operations. As shown in Table 1, the deposit request for operation 100, the deposit request for operation 200 and the operation request for operation 300 may be acknowledged out of order with which the operations were requested. As a result, the asset database 140 value, and thus the workflow value, diverge from the true value of assets available in a particular user account.

In some embodiments, the permission queue of the workflow service 120 may identify the tokens and/or number of tokens subject to the workflow of the event request 102 and lock the tokens and/or number of tokens from use for subsequent movements until the event request 102 has been either approved or rejected. Table 2 below shows an example illustrating using the workflow service 120 to provide the source of truth. As shown in Table 2, while the asset database 140 shows a lag in updating the value available to the user account, the workflow service 120 can ignore the lag to show the true value, and thus approve or reject operations before submission to the blockchain 150 and recordation in the asset database 140.

Accordingly, in some embodiments, the workflow service 120 may maintain an event log record database for a particular user. In some embodiments, the event log record database may record a token quantity and an operation requested via the event request 102. In some embodiments, the event request 102 may include additional data attributes, such as, e.g., an operation type, a destination token storage for a movement, a source token storage for a movement, a user identifier, a transaction identifier, among other data attributes or any combination thereof.

Therefore, in some embodiments, as multiple event requests 102 are received, the workflow service 120 may record the token quantity of each event request 102 to determine a transaction queue token quantity indicative of a total number of tokens subject to one or more operations for a given token storage of a given user. In some embodiments, the transaction queue token quantity may be used to automatically approve and/or reject subsequent event requests 102 based on a comparison of the transaction queue token quantity and a token quantity balance in the given token storage. If the transaction queue token quantity is equal to or exceeds the token quantity balance, the workflow service 120 may automatically reject the subsequent event request, effectively locking the tokens subject to existing event requests 102 in the transaction queue. As a result, the user is prevented from requesting operations using more tokens than are available in the given token storage. Where the transaction queue token quantity is less than the token quantity balance, the workflow service 120 may determine a first permission approving the event request 102 as a valid event request 102.

In some embodiments, the event requests 102 in the transaction queue may be passed to the back-end service 130 via one or more task-related messages 104 for processing in the order in which they were received. In some embodiments, the task-related message(s) 104 may include, e.g., one or more tasks identified by the workflow service 120 as associated with a particular event request 102, such as, e.g., an operation request for an account operation, an operation acknowledgement approving an account operation, an operation rejection rejecting an account operation, among other task-related messages 104 for performing tasks to carry out an event request 102, or any combination thereof.

In some embodiments, the processing of the task-related message(s) 104 may include operation instructions 105 to the asset database 140, the blockchain 150 or both. For example, in some embodiments, where the workflow service 120 approves an event request 102 and enters the event request 102 into the transaction queue, an associated task-related message 104 is sent to the back-end service 130. As a result, the back-end service 130 may generate an operation initiation instruction 105 to the blockchain 150 to cause the blockchain 150 to perform the movement of tokens according to the task-related message(s) 104. In some embodiments, the operation initiation instruction 105 may specify the operation to be performed related to tokens of the user's token storage. Accordingly, in some embodiments, the operation initiation instruction 105 may include data attributes such as a token quantity, an operation type, a source token storage, a destination token storage, a transaction identifier, among other data attributes or any suitable combination thereof.

In some embodiments, based on the operation type, the operation initiation instruction 105 may cause the blockchain 150 to initiate a smart contract 151 for performing the operation. In some embodiments, the operation type may include, e.g., a token redeem, a token deposit, a token transfer, among other operation types or any combination thereof. In some embodiments, a token redeem operation may cause a smart contract 151 for burning tokens (e.g., erasing tokens from the blockchain), and thus removing the tokens from the token storage of the user. As a result, the smart contract 151 and/or the back-end service 130 may issue an operation initiation instruction 105 to the asset database 140 to provide assets represented by the tokens to the user, e.g., in the user's account in the asset database 140. Additionally, in some embodiments, a token deposit operation may cause a smart contract 151 for minting tokens (e.g., producing new tokens on the blockchain), and thus adding the tokens from the token storage of the user. As a result, the smart contract 151 and/or the back-end service 130 may issue an operation initiation instruction 105 to the asset database 140 to remove assets represented by the tokens from the user, e.g., from the user's account in the asset database 140.

In some embodiments, a token transfer operation may cause a smart contract 151 to move tokens from a first token storage (the source token storage) to a second token storage (the destination token storage). As a result, the transfer of tokens from the first to the second token storage may cause a movement of assets from a first user account to a second user account associated with users of the first token storage and the second token storage, respectively. Alternatively, in some embodiments, the token transfer operation may cause a smart contract 151 to perform a token redeem operation for the first token storage to thereby remove a corresponding quantity of assets from the user account. The quantity of assets may then be transferred via the asset database 140 to a second user account associated with the second token storage, and the same or a different smart contract 151 may perform a token deposit operation to mint tokens on the blockchain in the second token storage.

In some embodiments, to generate the operation initiation instruction 105 for each movement of assets in the asset database 140, the smart contract 151 may specify the user account associated with each token storage of the movement of tokens. Accordingly, in some embodiments, the smart contract 151 may employ a mapping of user accounts to user token storages (e.g., wallets) as illustrated in FIG. 1B. In some embodiments, User A may have a User A Account 1 143 in the asset database 140 mapped to a User A wallet 1 153 on the blockchain 150. Similarly, User A may have a User A Account 2 144 in the asset database 140 mapped to a User A wallet 2 154 on the blockchain 150, User B may have a User B Account 1 145 in the asset database 140 mapped to a User B wallet 1 155 on the blockchain 150, User C may have a User C Account 1 146 in the asset database 140 mapped to a User C wallet 1 156 on the blockchain 150, etc. for each account of each user in a one-to-one manner. Similarly, in some embodiments, there may be an omnibus account 142 in the asset database 140, e.g., associated with a financial entity (e.g., bank, mortgage company, lender, credit agency, credit union, etc.) or other asset management entity or any combination thereof. The omnibus account 142 may be mapped to a contract total supply 152 that specifies a total number of tokens on the blockchain 150. Accordingly, the smart contract 151 may specify account operations based on token operations performed on the blockchain 150 in order to allow the back-end service 130 to match operations in the asset database 140 to the immutable ledger of the blockchain 150.

In some embodiments, the blockchain 150 may include one or more private and/or private-permissioned cryptographically-protected, distributed databased such as, without limitation, a blockchain (distributed ledger technology), Ethereum (Ethereum Foundation, Zug, Switzerland), and/or other similar distributed data management technologies. For example, as utilized herein, the distributed database(s), such as distributed ledgers ensure the integrity of data by generating a digital chain of data blocks linked together by cryptographic hashes of the data records in the data blocks. For example, a cryptographic hash of at least a portion of data records within a first block, and, in some cases, combined with a portion of data records in previous blocks is used to generate the block address for a new digital identity block succeeding the first block. As an update to the data records stored in the one or more data blocks, a new data block is generated containing respective updated data records and linked to a preceding block with an address based upon a cryptographic hash of at least a portion of the data records in the preceding block. In other words, the linked blocks form a blockchain that inherently includes a traceable sequence of addresses that can be used to track the updates to the data records contained therein. The linked blocks (or blockchain) may be distributed among multiple network nodes within a computer network such that each node may maintain a copy of the blockchain. Malicious network nodes attempting to compromise the integrity of the database must recreate and redistribute the blockchain faster than the honest network nodes, which, in most cases, is computationally infeasible. In other words, data integrity is guaranteed by the virtue of multiple network nodes in a network having a copy of the same blockchain. In some embodiments, as utilized herein, a central trust authority for sensor data management may not be needed to vouch for the integrity of the distributed database hosted by multiple nodes in the network.

In some embodiments, the exemplary distributed blockchain-type ledger implementations of the present disclosure with associated devices may be configured to affect transactions involving Bitcoins and other cryptocurrencies into one another and also into (or between) so-called FIAT money or FIAT currency and vice versa.

In some embodiments, the exemplary distributed blockchain-type ledger implementations of the present disclosure with associated devices are configured to utilize smart contracts that are computer processes that facilitate, verify and/or enforce negotiation and/or performance of one or more particular activities among users/parties. For example, an exemplary smart contract may be configured to be partially or fully self-executing and/or self-enforcing. In some embodiments, the exemplary inventive asset-tokenized distributed blockchain-type ledger implementations of the present disclosure may utilize smart contract architecture that can be implemented by replicated asset registries and contract execution using cryptographic hash chains and Byzantine fault tolerant replication. For example, each node in a peer-to-peer network or blockchain distributed network may act as a title registry and escrow, thereby executing changes of ownership and implementing sets of predetermined rules that govern transactions on the network. For example, each node may also check the work of other nodes and in some cases, as noted above, function as miners or validators.

In some embodiments, based on the operation initiation instruction(s) 105 and the balance of tokens in each token storage associated with a movement of tokens, the operations of the existing event requests 102 in the transaction queue may be approved and/or rejected on the blockchain 150. As a result, the blockchain 150 produce a write permission determination regarding the movement of the tokens with respect to the associated token storages. In some embodiments, the write permission determination may include, e.g., the transaction details of a new block in the ledger, an indication of a permission or rejection, among other data indicative of whether the operation is successful or unsuccessful or any combination thereof.

In some embodiments, the back-end service 130 may provide the write permission determination to the workflow service 120, e.g., via a task-related message 104. The workflow service 120 may then update the event log record database to reflect a completed event request of the associated event request 102 in the event log record database. In some embodiments, where the write permission determination results in the associated event request 102 being successfully processed to effectuate the movement of tokens, the event log record database may be updated to release the tokens from the event log record database, thus removing the tokens subject to the associated event request 102 from the total number of tokens of the event log record database. As a result, the event log record database is synchronized with the token storage to provide an accurate and efficient source of truth for allowing or rejecting event requests 102 prior to submission to the back-end service 130 and blockchain 150, thus preventing the attempted use of tokens that are already subject to operations associated with existing event requests 102.

FIG. 2 illustrates a workflow orchestration for event request permission via a workflow service for controlling blockchain events in accordance with one or more embodiments of the present disclosure.

In some embodiments, upon receiving an event request 102, the front-end service 110 may determine a permission workflow for approving the event request. In some embodiments, the event request may be provided at step 1 via a first node user device, termed a maker device 101A. The event request may include a request to perform one or more operations relative to a maker token storage.

At step 2, the front-end service 110 may transmit a balance inquiry request to the asset database 140 based on the event request. In some embodiments, the event request may include a data attribute including a number of tokens needed for effectuating a movement of tokens. In some embodiments, the movement of tokens corresponds to an account operation relative to a user account associated with the maker device 101A. Thus, the front-end service 110 may issue the balance inquiry request to query a balance of assets in the user account.

At step 3, the asset database 140 may return the asset balance in a balance inquiry response. In some embodiments, the balance inquiry response may specify a quantity or value of assets associated with the user account of the maker device 101A.

At step 4, where the quantity or value of assets associated with the user account is greater than the number of tokens needed for effectuating the movement of tokens of the event request, the front-end service 110 may produce a permission request. In some embodiments, the permission request may include, e.g., the data attributes of the event request, the quantity or value of assets associated with the user account, among other suitable data attributes characterizing the movement of the number of tokens. In some embodiments, the front-end service 110 may communicate the permission request to the workflow service 120 for entry of the event request into a transaction queue of the workflow service.

At step 5, the workflow service 120 may perform an event validation based on the permission request. In some embodiments, the event validation may include appending the data attributes of the event request to the transaction queue and updating an event log record database and transaction queue token quantity. In some embodiments, based on the transaction queue token quantity, the number of tokens associated with the event request and a number of tokens in the maker token storage, the workflow service 120 may approve the permission request.

At step 6, the workflow service 120 may send a permission response to the front-end service 110 specifying that the movement of tokens is approved.

At step 7, in response to the permission response, the front-end service 110 may provide the permission response to an approver device 101B. In some embodiments, the approver device 101B may include, e.g., a computing device associated with a supervisory or administrative node of the hybrid blockchain platform 100. In some embodiments, the approver device 101B may be responsible for verifying permission responses, e.g., where the permission response includes an exception or error. Accordingly, an approver user at the approver device 101B may select via a suitable permission GUI presented by the front-end service 110, the data attributes associated with the movement of the quantity of the tokens with respect to the maker token storage.

At step 8, where the approver user approves of the data attributes, the approver user may select to approve the movement via the permission GUI, causing the approver device 101B to send a permission to the front-end service 110. In some embodiments, the permission may include an approved event request including the data attributes of the movement and/or an indication of the permission.

At step 9, the front-end service 110 may communicate the permission to the workflow service 120. In response, at step 10, the workflow service 120 may return a permission acknowledgement acknowledging receipt of the permission.

At step 11, upon sending the permission acknowledgement, the workflow service 120 may issue an initiate event command to the back-end service 130. In some embodiments, the initiate event command may include, e.g., one or more task-related messages 104 to trigger processing the event request and the movement of the number of tokens. In some embodiments, the task-related message(s) 104 may include, e.g., one or more tasks identified by the workflow service 120 as associated with the event request. In some embodiments, the initiate event command may cause an event processing 200 sequence associated with the operations of the event request, such as, e.g., triggering a smart contract associated with the movement of the quantity of the tokens on the blockchain 150. In some embodiments, the issuance of the initiate event command may also cause the workflow service 120 to update the transaction queue to remove the event request from the event log record database and remove the number of tokens from the transaction queue token quantity.

At step 12, the front-end service 110 may confirm to the maker device 101A the event processing 200, e.g., via an event acknowledgement. In some embodiments, the event acknowledgement may cause an update to the event control GUI of the maker device 101A to reflect the movement of the quantity of the tokens and/or update a displayed availability of tokens in the maker token storage.

FIG. 3 illustrates another workflow orchestration for event request permission via the workflow service for controlling blockchain events in accordance with one or more embodiments of the present disclosure.

In some embodiments, upon receiving an event request 102, the front-end service 110 may determine a permission workflow for approving the event request. In some embodiments, the event request may be provided at step 1 via a first node user device, termed a maker device 101A. The event request may include a request to perform one or more operations relative to a maker token storage.

At step 2, the front-end service 110 may transmit a balance inquiry request to the asset database 140 based on the event request. In some embodiments, the event request may include a data attribute including a number of tokens needed for effectuating a movement of tokens. In some embodiments, the movement of tokens corresponds to an account operation relative to a user account associated with the maker device 101A. Thus, the front-end service 110 may issue the balance inquiry request to query a balance of assets in the user account.

At step 3, the asset database 140 may return the asset balance in a balance inquiry response. In some embodiments, the balance inquiry response may specify a quantity or value of assets associated with the user account of the maker device 101A.

At step 4, where the quantity or value of assets associated with the user account is greater than the number of tokens needed for effectuating the movement of tokens of the event request, the front-end service 110 may produce a permission request. In some embodiments, the permission request may include, e.g., the data attributes of the event request, the quantity or value of assets associated with the user account, among other suitable data attributes characterizing the movement of the number of tokens. In some embodiments, the front-end service 110 may communicate the permission request to the workflow service 120 for entry of the event request into a transaction queue of the workflow service.

At step 5, the workflow service 120 may perform an event validation based on the permission request. In some embodiments, the event validation may include appending the data attributes of the event request to the transaction queue and updating an event log record database and transaction queue token quantity. In some embodiments, based on the transaction queue token quantity, the number of tokens associated with the event request and a number of tokens in the maker token storage, the workflow service 120 may approve the permission request.

At step 6, the workflow service 120 may send a permission response to the front-end service 110 specifying that the movement of tokens is approved.

At step 7, in response to the permission response, the front-end service 110 may provide the permission response to an approver device 101B. In some embodiments, the approver device 101B may include, e.g., a computing device associated with a supervisory or administrative node of the hybrid blockchain platform 100. In some embodiments, the approver device 101B may be responsible for verifying permission responses, e.g., where the permission response includes an exception or error. Accordingly, an approver user at the approver device 101B may select via a suitable permission GUI presented by the front-end service 110, the data attributes associated with the movement of the quantity of the tokens with respect to the maker token storage.

At step 8, where the approver user rejects the data attributes, the approver user may select to reject the movement via the permission GUI, causing the approver device 101B to send a rejection to the front-end service 110. In some embodiments, the rejection may include a rejected event request including the data attributes of the movement and/or an indication of the rejection.

At step 9, the front-end service 110 may communicate the rejection to the workflow service 120. In response, the workflow service 120 may update the transaction queue to remove the event request from the event log record database and remove the number of tokens from the transaction queue token quantity. In some embodiments, at step 10, the workflow service 120 may then return a permission rejection acknowledging the rejection.

At step 11, upon sending the permission rejection, the front-end service 110 may confirm to the maker device 101A the permission rejection, e.g., via an update to the event control GUI of the maker device 101A to reflect a rejection of the movement of the quantity of the tokens.

FIG. 4 illustrates a workflow orchestration for a token redeem event request and event processing based on the workflow service for controlling blockchain events in accordance with one or more embodiments of the present disclosure.

At step 1, the front-end service 110 may transmit a balance inquiry request to the asset database 140 to identify a balance of assets of a particular user account. Thus, the front-end service 110 may issue the balance inquiry request to query a balance of assets in the user account.

At step 2, the asset database 140 may return the asset balance in a balance inquiry response. In some embodiments, the balance inquiry response may specify a quantity or value of assets associated with a user account of a user device, such as a maker device.

In some embodiments, the front-end service 110 may receive, at step 3, an event request, e.g., from the user device 101, including a redeem request. In some embodiments, the event request may require permission before being acknowledged and provided to the event processing 200.

Accordingly, at step 4, the front-end service 110 may begin event processing 200 upon permission via the workflow service 120 (e.g., as illustrated in FIG. 2 above). In some embodiments, to perform event processing 200, the front-end service 100 may provide the redeem request to the back-end service 130. In some embodiments, the redeem request may include, e.g., the data attributes of the event request such as the quantity or value of assets associated with the user account, the quantity or value of tokens to be redeemed, a user identifier identifying the user and/or the user account, a transaction identifier, among other suitable data attributes characterizing the movement of the number of tokens in a redeem operation.

At step 5, the back-end service 130 may instruct, via a burn request, the blockchain 150 to perform a token movement corresponding to the asset movement. In some embodiments, the movement of tokens is to reflect the removal of assets, e.g., from the user account of the asset database 140, and thus includes a corresponding removal of tokens from the token storage by burning the tokens from the blockchain 150 using the smart contract 151. In some embodiments, rather burning the tokens, the burn request may include a transfer request form the token storage to an omnibus token storage or other custodial and/or omnibus token storing structure.

In some embodiments, the blockchain 150 may employ a smart contract 151 to perform the token burn at step 8. In some embodiments, the removal may include a movement to a custodial or omnibus token storage mapped to the omnibus account. In some embodiments, the removal is a burn of tokens, thereby removing the tokens from the blockchain 150.

At step 9, the blockchain 150 may return a burn response to the back-end service 130 to acknowledge the token burn and the change to the user's token storage.

In some embodiments, based on the data attributes of the event request, the back-end service 130 may initiate a transfer request at step 8. In some embodiments, as an exemplary illustration, step 7 is depicted as occurring after steps 5, 6 and 7, but in some embodiments, step 8 may be performed before or concurrently with any one or more of step 5, step 6 and/or step 7. In some embodiments, the transfer request is sent to the asset database 140 to request a movement of assets out of the user account such that the user may extract and use the assets outside of the user account. In some embodiments, the movement of assets may include a movement out of the user account into an omnibus account (see, e.g., the smart contract 151 mapping illustrated in FIG. 1B above). In some embodiments, the omnibus account is a custodian of assets to enable asset use with systems and entities outside of the asset database 140. For example, in order to withdraw money from an automated teller machine (ATM), the redeem request may cause the back-end service 130 to issue a transfer request from the user account to the omnibus account such that the omnibus account may provide an equivalent value in cash to the ATM for dispensation. The omnibus account may serve a similar role in transferring assets to another entity or account that is distinct from the omnibus account, the asset database 140 and/or the hybrid blockchain platform 100, such as another bank or other financial entity.

In some embodiments, upon completion of the transfer, at step 9 the asset database 140 may return a transfer response to the back-end service 130. In some embodiments, the transfer response may acknowledge a completion of an operation in the asset database 140 include the transfer for the redemption of tokens to extract assets from the user account.

At step 10, in response to the burn response, the back-end service 130 may confirm to the front-end service the redemption of tokens via a redeem response.

At step 11, in response to the redeem response, the front-end service 110 may confirm to the user device the event processing 200 including the redeem response. In some embodiments, the redeem response may cause an update to the event control GUI of the user device 101 to reflect the redemption of the quantity of the tokens and/or update a displayed availability of tokens in the token storage less the redeemed tokens.

FIG. 5 illustrates a workflow orchestration for a token deposit event request and event processing based on the workflow service for controlling blockchain events in accordance with one or more embodiments of the present disclosure.

At step 1, the front-end service 110 may transmit a balance inquiry request to the asset database 140 to identify a balance of assets of a particular user account. Thus, the front-end service 110 may issue the balance inquiry request to query a balance of assets in the user account.

At step 2, the asset database 140 may return the asset balance in a balance inquiry response. In some embodiments, the balance inquiry response may specify a quantity or value of assets associated with a user account of a user device, such as a maker device.

In some embodiments, the front-end service 110 may receive, at step 3, an event request, e.g., from the user device 101, including a deposit request. In some embodiments, the event request may require permission before being acknowledged and provided to the event processing 200.

Accordingly, at step 4, the front-end service 110 may begin event processing 200 upon permission via the workflow service 120 (e.g., as illustrated in FIG. 2 above). In some embodiments, to perform event processing 200, the front-end service 100 may provide the deposit request to the back-end service 130. In some embodiments, the deposit request may include, e.g., the data attributes of the event request such as the quantity or value of assets associated with the user account, the quantity or value of tokens to be deposited, a user identifier identifying the user and/or the user account, a transaction identifier, among other suitable data attributes characterizing the movement of the number of tokens in a deposit operation.

In some embodiments, based on the data attributes of the event request, the back-end service 130 may initiate a transfer request at step 5. In some embodiments, the transfer request is sent to the asset database 140 to request a movement of assets into the user account from outside of the user account. In some embodiments, the movement of assets may include a movement into the user account from an omnibus account (see, e.g., the smart contract 151 mapping illustrated in FIG. 1B above). In some embodiments, the omnibus account is a custodian of assets to enable asset use with systems and entities outside of the asset database 140. For example, in order to deposit money at an automated teller machine (ATM), the deposit request may cause the back-end service 130 to issue a transfer request from the omnibus account to the user account based on cash deposited at the ATM, such that the omnibus account may provide an equivalent value in assets to the user account. The omnibus account may serve a similar role in transferring assets from another entity or account that is distinct from the omnibus account, the asset database 140 and/or the hybrid blockchain platform 100, such as another bank or other financial entity.

In some embodiments, upon completion of the transfer, at step 6 the asset database 140 may return a transfer response to the back-end service 130. In some embodiments, the transfer response may acknowledge a completion of an operation in the asset database 140 including the transfer for the deposit of tokens into the user account.

At step 7, the back-end service 130 may instruct, via a mint request, the blockchain 150 to perform a token movement corresponding to the asset movement. In some embodiments, as an exemplary illustration, step 7 is depicted as occurring after steps 5 and 6, but in some embodiments, step 7 may be performed first or concurrently with step 5 and/or step 6. In some embodiments, because the assets are transferred into the user account, the movement of tokens is to reflect the addition of assets, and thus includes a corresponding addition of tokens into the token storage.

In some embodiments, the blockchain 150 may employ a smart contract 151 to perform the token mint at step 8. In some embodiments, the addition of tokens may include a movement from a custodial or omnibus token storage mapped to the omnibus account. In some embodiments, the addition of tokens is a mint of tokens, thereby creating the tokens on the blockchain 150 and assigning the created tokens to the token storage mapped to the user account.

At step 9, the blockchain 150 may return a mint response to the back-end service 130 to acknowledge the token mint and the change to the user's token storage.

At step 10, in response to the mint response, the back-end service 130 may confirm to the front-end service the deposit of tokens via a deposit response.

At step 11, in response to the deposit response, the front-end service 110 may confirm to the user device the event processing 200 including the deposit response. In some embodiments, the deposit response may cause an update to the event control GUI of the user device 101 to reflect the deposit of the quantity of the tokens and/or update a displayed availability of tokens in the token storage including the deposited tokens.
